Excuse me, is Mondeo winning uncovered refueling system safe? Who can give me a brief introduction?

Mondeo's patented new technology "Capless Refueling System" is Ford's first in the automobile market. At present, in the auto market at the same level, Mondeo-Zhisheng is unique in the uncovered refueling technology. As the killer of Mondeo, the uncovered refueling system has the dual characteristics of convenience and safety. The convenience of this technology is that there is only a cover outside it, which will pop up when refueling. The staff at the gas station can refuel directly without the owner getting off the bus, which saves the owner the trouble. If the vehicle can't reach the gas station, it needs to refuel at the roadside, and the winning owner of Mondeo doesn't have to worry about manual refueling. Mondeo-Zhisheng fuel tank is equipped with an auxiliary refueling funnel, which can be easily refueled by simply inserting a refueling nozzle. The safety of Mondeo-Zhisheng uncovered refueling system is mainly reflected in the automatic identification function of its refueling gun. When in use, insert the standard oil gun into the oil hole. If the nozzle size is correct, the spring loader will open. Although the size of the spring plug is very small, its automatic identification function for gasoline gun and diesel gun can provide maximum safety when refueling and avoid the damage to the engine caused by accidental refueling. In addition, this system also makes it cleaner and more convenient to pull out the refueling gun without spilling gasoline. For Ford Europe, the latest flagship product, the unique design of the uncovered refueling system not only embodies the winning technology content of Mondeo, but also is very humanized, showing Ford's exquisite German technology and advanced automobile technology in details.
